hello fellas, I've been trying to increase the frequency of my haswell, but something funky is going on (I think)
all the way up to 4600 mhz for every voltage I increase the core the same increase in vIN stabilizes it.
but here is the problem, I think: while for 4600 mhz I manage to get along with 1.67 vIN, for 4700 mhz even 1.9 appears to be insufficient
the mobo is far from steallar (asrock z87 e3, it use 3pin mosfets for cpu power) but the whole thing is on water so mosfets on water (50 C) cpu on water (at 4700 1.35v could get to 80C)
what do you think ? limit of the power system ?
I try increase/decrease the vcore but here is what is hapen: when decrease below 1.34 it BSOD verry fast (interrupt was not received within the necessary time on the secondary processor). when increase above 1.35 is also BSOD fast with the same message. it managed to last for about an hour or two at 1.34/1.35.
I try 1.36v with 2.0v input, it BSOD in 50 minutes
im testing with old version of prime95 which is without AVX using the small FFT mode
